Application filed June 29, 1912. Serial No. 706,739.'

To auw/omit may concern.' 4 'Y Be itknoW-n that I, FREDERICK E. CoWnLL,

a citizen of the Unitedv States, residing at Copper Gity, Province ofBritish Columbia, Canada, have invented certain .new and use# fulImproveinents in Saw-Sets, oftvhich the following-:is a specification.

This invention.o relates to hand operated s awsets, )and has oritsobject the provision of a tool of simple construction which may beoperated Without fatig e to ettiand dnrabiiityoirthe san'e iiiay be inzodrin the accom- W'ill be hereinafter fully describedl the ncveljfeaturesbeing subseqnentlipointed out iifthv'eclaims following they descptio lIn' 'tle drawinesi-gine/las a sectional elevation of a saw et ,embodyingmy inventienqFig. 2 is a sectional view on the; line.

2 il/Fig. 15; Fig. 3 is' a detailfront elevathe anvil; 4 is adetailperspec- .t'iv .'vievv of the anvil adjusting device.

Iii' carrying out "my invention, l employ a body 1 which may be cast inone integral i l.pice and consists of a substantially cylindrieal mainlportion having .ahandle 2 eX- tending'downwardly from its rear end andis-.provided at its front end with a depending/saw supportingand/bracing headA 3. A'

lug or bracket 4 depends from thernain portion of the body 1, and a set'screw 5 is mounted in the saidv lug or bracket to bearI 4against the sawblade,indicated at 6, and ,clamf'the [same firmly against the' head 3 soasito support the same in proper posibetvveen the die and the anvil.

' 'Within the main portion of the body 1 is a longitudinal chamber. 7openingiat its front end'above and in' advance of the lug or bracket iIand opening 'at its rear end through .the vunder side of the body.Within said chamber 7 are transverse Webs or partitions .8 which formsupports for the die or hammer 9, said die, hammer, or setting pin beingnormally held retracted W1thin the chamber by a spring 10 coiled aroundthe pin bearing against the rfront web ciently set the teeth of a saw at,any desired vor partition 8 and against a sto-p11 in the pin, asclearly shown. The sropll is con'- Patented Mai'. 1 1, H513.

vcniently a small pin inserted'thrmigh. the

setting pin or die, and to provide a. 'Wider support for the end of thespring, a Washer- 1:2 may be fitted aroundthe-die against' the saidsto-p. rEhe frontend of tie' die' orv setting pin is beveled to'engagethe saw teeth',`

land the rear end thereof beveled to bear agalnst the upper1 end-of an'operating lever 13 fulcrnmed. atv let 'withinthe chamber7 at the lowerrear end thereof. The upper end of the llever 13 is provided With icooperative relation to the die.. The bolt or Screivlf? is provided.with athumb nut so f angles, so that, by properly adjust-ing the anvil,a iace vcorresponding-to vthe angle'tobe. given the saw tooth maybebrought in.

20 on its outer -endA which may be turned home against the head 53 tothereby clamp the. anvil in'its adjusted position. The anvil" 'mayberaised or lowered so as to give the saw a coarser or finer .Set.by'n'ieau's of .the

regulating device 21 consisting of a disk or J plate 22 having,` a'centralfopening to t 'around the screw -17`betWeen the head 8 andtheanvil and a supporting' lip-or Wing'QS connected with the edgeof saiddisk or plate and adapted to project over vthe upperedge of the head 3..The' edge of the-head is pro vided, immediately adjacentits center, withthe oppositelyAr extending bevel surfaces '24,'

25', which extend in opposite directionsfrom the central vertical lineof the head andare disposed at different angles. lVhen'thezlip I 23rests in the angle formed by the surfaces 24, 525, the'screw' or bolt.17 will .be :1t-the.

lower end ofthe slot 16, andthe anvil Will consequently be in its'lovvest'position so that face 24,'the screvv or bolt 17 lWillbe'broughtto the center of the slot 16, While, if the'lip be caused to ride up thesurface 25to the vthe coarsest set Will be given the saw. lf tlie lip beturned so as lto ridelup the snr-v upper end thereof the screuT or bolt17 will be raised to the upper end ot the slot 16.

In this simple manner, I provide for adjustingl the anvil so as topermit the saw' being given a coarse or line set, as may be desired. Theoperation of the device is thought to be clear from the foregoingdescriptionf" The tool is engaged over the edge of the saw, as indicatedin Fig. l, and the thumb screu7 5 is turned home against the saw bladeso as to hold 'it iirmly against the head 3.

,The anvil7 having been previously adjusted hile'the tooth is being set,it should befsoadjusted so 'to permit the saw being slipped through thetool so as to bring another tooth into position to be set Withoutrequiring,1 manipulation of the screw each time a tooth is set. Theadjustment ot the anvil is very quickly accomplished, and when the anvilhas been adjusted, it will be securely held so that it will not bedislodged during the operation of the tool. The rotation of the anvilbrings any desired :tace thereof in operative relation to the settingpin so that thetooth ma be set at any angle While the verticaladjustment of ,the anvil permits the device to ac `commodate saw teethof any depth.

What claim is l. A saw set comprising a body. having a saw supportingand bracing head depending from its front end` and p-rovided'with avertical slots` an anvihla member projecting from the said anvil throughthe said slot, and an anvil support engaging said member and restingupon the head and adapted to adjust the anvil vertically.

Q. In a saw set, the combination of a body havingI a head at its frontend provided with a vertical slot, an anvil disposed adjacent the saidhead7 a pivot for said anvil extending through said slot and adapted torotatably adjust the anvil, means for se* curing said pivot in theposition to Which it may be rotated, and an anvil support engaging saidpivot and resting upon the head.

A saw set comprising a body, a head at its front end provided With avertical slot, an anvil, a pivot for the anvil projecting through saidslot, and a support tor the anvil engaging. said pivot and provided Witha lip overhangingthe head, the head bei-.ng

provided withl diverging beveled surfaces ot' different .degrees ot'inclination to be engaged by said lip.

In testimony whereof I aix my signature in presence of two Witnesses.
